MECHANISM FOR REVERSING MOTION.

SPECIFICATION forming part of Letters Patent No. 260,285, dated June2'2, 1882. Application filed March 15, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN DANCEL, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Mechanism for Reversing Motion, of whichthe following is a specification.

This invention consists in the combination of the following devices apulley mounted on the driving-shaft, two sectional pulleys mounted onthe driven shaft, each of said sectional pulleys consisting of a sectionwhich revolves loosely on the driven shaft and of a section which isfeathered to said driven shaft, a hub connecting the featheredpulley-sections, a lever engaging with said hub, a cross belt extendingfrom the driving-pulley over the loose section of one pulley, and anopen belt extending from said driving-pulley over the loose section ofthe other pulley, said belts being of such a width that their edgesextend beyond the inner edges of the loose pulley-sections, so that whenone of the feathered pulley-sections is moved up against thecorresponding loose section that portion of the belt which projectsbeyond the inner edge of said loose section acts upon the featheredsection and the driven shaft is caused to revolve in one direction, andby moving the other feathered section up against the correspondingloosesection the motion of the driven shaft is reversed. With theshipping-lever is combined a sort of a toggle mechanism for locking thefeathered pulleysections in the required position.

In the accompanying drawings, Figure 1 represents a front view of mymechanism. Fig. 2 is a longitudinal section of the samcon alarger scalethan the previous figure.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the driving-shaft, on which ismounted the pulley B.

O is the driven shaft, which is to turn alternately in one and then inthe opposite direction. On this driven shaft are mounted two pulleys,each of which consists of a section D or D and of a section E or E, thesections D D being mounted loosely on the shaft 0, while the sections EE are connected to the same by a feather-key, a, so that they can slideon said shaft toward and from the loose sections, while the shaft iscompelled to revolve with the inner edges of said pelts project beyondthe inner edges of the corresponding loose sections to a distance equalto the face of the corresponding feathered section,-as shown in Fig.2.

1f the feathered section E is moved up against the corresponding loosesection D, the belt H bears upon the face of said loose section and theshaft 0 revolvesin one direction say that indicated by the arrows inFig. 1. If, now,the feathered section E is moved up against the loosesection D, the feathered section E being at the same time removed fromthe loose section D, the cross-belt H is brought to act on the featheredsection E and the motion of the shaft 0 is reversed.

The shipping-lever G is made in the form of a bell-crank lever, whichturns on a pivot, 12, and the arm 0 of which is provided with a slot, n,containing a slide, 6, which is pressed outward away from the fulcrum bby a spring,

f. From the slide 0 projectsa pin, 9, which engages with a lover, I,that has its fulcrum on a pivot, h. When the lever I is brought into theposition shown in Fig. 2 the feathered section E is moved up against theloose section D, and the shipping-lever G becomes locked, since the pin9 is thrown above the line drawn through the center of the pivots b h,and consequently some power is required to disturb the position of theshipping-lever. If the lever I is moved in the direction of the arrowmarked near it in Fig. 2, the spring f is compressed, and as the pin 9passes beneath the line drawn through the pivots b h the shipping-leverG is shipped and the feathered section E is moved up against the loosesection D, the motion of the shaft (J is reversed, and theshipping-lever is again locked. v

This mechanism is particularly adapted to metal-planing machines inwhich the bed reciprocates and the lever I is moved by the direct actionof said bed; but my mechanism can also bcusedin many other machineswhere a self-acting reversing-gear is required.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore described, of thedriving-pulley, the loose pulley-sections, and the featheredpulleysections mounted on the driven shaft, the cross-belt H and theopen belt H, extending round the loose pulley-sections and projectingbeyond their inner edges, and the shippinglever acting on the featheredpulley-sections.

2. The combination, substantially ashereinbefore described, of thedriving-pulley, the loose pulley-sections, and the featheredpulleysections mounted on the driven shaft, the crossbelt H and the openbelt H, extending round the loose pulley-sections and projecting beyondtheir inner edges, the shipping-lever act- 20 ing on the featheredpulley-sections, and an automatic locking mechanism.

3. The combination, substantially as hereinbefore described, of theshippin g-lever mounted on a pivot, b, the slide 6, fitted to the arm aof 25 said shipping-lever, the spring f, acting on the slide, the pin g,projecting from said slide, and the lever I, mounted on the pivot h andengaging with the pin g.

In testimony whereof I have hereunto set my 0 hand and seal in thepresence of two subscribing witnesses.
